Definitions

  • This invention relates generally to hinged structures which can be readily folded into a compact form and which, after having been opened, can be converted into a load-supporting configuration.
  • a foldable structure having a plurality of plates which may be generally flat and which are hinged together along at least two mutually perpendicular axes.
  • the hinged plates can be readily folded into a compact configuration.
  • one row of plates is swung on its hinge(s) so as to be out of the plane of the other row or rows of plates. the resulting configuration becomes quite rigid and non-foldable.
  • the plate members may have any suitable geometrical form, e.g., triangular, rectangular, cylindrical or trapezoidal.
  • the plates may be continuous sheets of material or may be formed as a frame having openings extending through the thickness dimension thereof. It is also to be understood that the area and thickness of the plates is not a critical feature of the folding structures according to the present invention and are to be chosen in accordance with the requirements and size of the final rigid structure to be created when the folded structure is deployed.
  • the hinges can be formed in a variety of ways from various available materials.
  • the folded structures will generally comprise more than a single row and a single column of hinged plates.
  • the number of rows and columns extending parallel to and adjoining each other is also determined in accordance with the ultimate design of the final rigid structure once it is deployed.
  • stabilizing means may typically comprise lengths of cables, rods, hinge pins, ropes, cords, springs, etc.
  • FIG. 1(a) there is illustrated the basic structure from which the principles of the various other embodiments described herein will be explained. It is seen to include a plurality of plates arranged in two rows of five columns each and identified by numerals 1-1, 1-2, 1-3, 1-4 and 1-5 in row 1 and numerals 2-1, 2-2, 2-3, 2-4 and 2-5 in row 2.
  • Each of the plates is illustrated as being generally rectangular with all four edges being notched to create a pattern of spaced teeth 16 separated by grooves 17. As will be apparent from the following description, the plates need not be rectangular.
  • Each of the teeth 16 has a longitudinal aperture 18 passing therethrough for receiving a hinge pin as at 19. It is to be further noted that the teeth on one edge of each plate are configured to mate with the grooves on the adjacent plate such that, when the pin 19 is inserted through the aligned apertures 18, a hinge connection results.
  • the size and thickness of the plates 1-1, 1-2, etc., are not critical and the plates themselves can be fabricated from a variety of materials, such as metals, plastics, etc.
  • the hinges can be fabricated from a variety of materials and can assume various shapes.
  • Figures 2(a) and 2(b) illustrate a configuration of a collapsible, foldable structure which, when deployed, can function as a bridge whereby personnel or vehicles readily traverse a stream or the like. While the Figures 2(a) shows the structure partially accordion folded, it is obvious that the structure can also be rolled in a spiral configuration to render it compact.
  • the bridge comprises a plurality of plate members 30 hinged to one another and having side flaps 31 and 32 also secured by hinges to the side edges thereof.
  • the hinges are illustrated schematically by the symbol indicated by numeral 33 in Figure 2(a).
  • This figure also shows the bridge configuration in a partially flattened, partially folded form prior to being erected.
  • a plurality of rigid plates 35 have side flaps 36 and 37 joined thereto by hinges having teeth 16 and grooves 17 meshed with one another and joined by a hinge pin (not shown).
  • adjacent side flaps 36 are hinged together along the transverse edges thereof as at 38.
  • the reader can readily visualize how this structure can be laid flat by rotating the side flaps 36, 90° from the position illustrated in Figure 3 so that the side flaps 36 lie either in the plane of the plates 35 or directly beneath it. Then, by folding the plates 35 so as to rotate about the hinges 38, the assembly can be collapsed into a compact configuration.
  • a hinge extend continuously the entire width of the structure, the hinges 38 between flap segments providing the axis of rotation for folding.
  • a rigid structure results.
  • the latching arrangement is seen to include a first pair of linkages 39 and 40 pivotally joined between the side plates 36 and the top plates 35 at one or both ends of the structure and coupled to a second pair of linkages joining plates 35 to side plate 37 by a spring 41.
  • Figure 4 illustrates a collapsible, foldable ladder which may be used to ascend to or descend from a predetermined height.
  • the structure is seen to include a plurality of plates 42, each having a central opening 43 formed through the thickness dimension thereof and side flaps 44 and 45 individually joined thereto by hinges.
  • the side plates 44 and 45 themselves also include hinges 46 joining adjacent side plates to one another. As before, this construction permits the side flaps 44 and 45 to be rotated inwardly toward one another beneath and parallel to the plane of the apertured plates 42, allowing accordion folding of the assembly about the side flap hinges 46.
  • Figures 5 - 8 illustrate the principles of the invention as applied to a stretcher 110 for transporting sick or injured persons.
  • poles 112 and 114 having handle grips 116 on the opposed ends thereof.
  • the poles 112 and 114 are made to pass through pole receiving loops 118, 120, 122 and 124 sewn along the side edges of a generally rectangular fabric sheet 126.
  • the fabric sheet may be attached along its longitudinal edges to the articulated poles by other means, such as screws, wedging in dove-tail grooves in the pole, Velco (Regd. T.M.) fasteners or other suitable means.
  • the articulated poles 112 and 114 are seen to include a plurality of segments 128, 130, 132 and 134 which are joined together in an end-to-end relationship by means of hinges 136, 138 and 140. While four such segments are illustrated, those skilled in the art will appreciated that a greater or fewer number of hinged segments can be utilized. As can perhaps best be seen in the view of Figure 6, each of the hinges is provided with a pin 142 which comprises an axis about which the adjacent pole segments swing relative to one another. The hinges further include cooperating stop means 144 - 146 which limits the rotation about the axle 142 to 180° or less. It is to be further noted from Figure 6 that adjacent hinges are oriented so as to operate in opposite directions.
  • segment 134 swings in a clockwise direction relative to segment 132 whereas segment 132 rotates in a counterclockwise direction with respect to segment 130. It is contemplated, however, that the hinges can be configured so that adjacent hinges may rotate in the same direction, depending upon the desired folding design selected for the stretcher.
  • the hinge axes 142 are oriented in alignment with a plane passing through the two articulated poles 112 and 114. Once fully extended, however, the poles 112 and 114 may be rotated by the porters 90° about their own longitudinal axis within the pole receiving loops 118 - 124 of the fabric sheet 126 such that the hinge axes 142 will no be perpendicular to the plane defined by the two parallel articulated poles 112 and 114. With the hinge axes thus oriented, the articulated pole segments are prevented from folding or collapsing against one another because any tendency to fold is restrained by the inelastic fabric sheet 126.
  • each of the articulated poles 112 and 114 there is provided on the endmost segments 128 and 134 of each of the articulated poles 112 and 114 a folding leg as at 148.
  • the leg is preferably ring-shaped and is coupled to the pole segment by a hinge 150 whose pivot axis extends generally parallel to the pole segment to which it is affixed.
  • the legs 148 are ring-shaped to accommodate attachment to standard racks designed into transport vehicles such as ambulances and helicopters.
  • a pair of transversely extending bar-like linkages 154 and 156 may be pivotally joined to the hinged legs 148 at pivot point 152.
  • Linkages 154 and 156 cooperate with the legs on the opposed side of the litter and may be jointed at their other ends to one another or, alternatively, to a centre stop member 157 to form an over-centre latch.
  • the articulated poles 110 and 112 are maintained in a spread condition when the linkage assembly is pushed to the "open" position.
  • the stretcher When the linkage arrangement is pulled in the "close" direction beyond their point of alignment and with the poles 110 and 112 being rotated so that the hinge axes 142 are perpendicular to the direction of an applied force, the stretcher can be completely collapsed and folded to a length approximately one-fourth its fully unfolded or extended size, assuming, of course, that four pole segments are hinged together in the manner illustrated. Where the poles are each of a greater number of equal length segments, the folded lengths will be correspondingly reduced.
  • Figure 8 illustrates the stretcher poles in their completely folded condition such as when it is being stored or transported.
  • the fabric 126 is not shown in Figure 8 in order to better view the structural members and hinges when folded.
  • an actual stretcher made in accordance with the present invention in its unfolded or extended condition, it has an overall length of 82 inches, a width of 22 inches and a height of 6 inches. When folded, however, as in Figure 8, the length become 20.8 inches, it width 7 inches and its height 5-1/2 inches, a size that can readily be carried on a backpack.
  • the stretcher weights only 10.5 pounds. Tests also have revealed that only six seconds are required to fully deploy it from its folded condition and seven seconds are required to refold it.
  • poles are shown as being of a circular cross-section, they can also be formed from square tubing.
  • the hinges 136, 138 and 140 may be precast from aluminium and welded to the tubes as indicated. Alternatively, they can be machined or otherwise integrally formed with the tubes.
  • the hinge plates or pole segments can be of equal or unequal lengths and can be fabricated from a choice of materials including various metals, metal alloys, plastics or wood. Extruded aluminium tubing is preferred for the stretcher embodiment because of its balance of strength and light­weight.
  • the hinges and poles of the stretcher can be made as one unit using a suitable die-mould casting technique.
  • the flexible sheet supported by the articulated poles need not necessarily be a cloth fabric, but may instead be plastic, fiber-reinforced plastic or even rigid plastic segments which are linked together by hinge elements to allow folding thereof.
  • the plates need not be rigid but can be flexible as with the stretcher embodiment.
